The observational study aims to improve understanding of Oral Health-Related Quality of Life (OHRQoL) among preschool children in the District of Portalegre, Portugal, by examining the roles of sociodemographic, behavioral, and parental psychosocial factors, as well as the child's oral health status. The study seeks to answer the following main research question: How do sociodemographic, behavioural, parental psychosocial factors, and the child's oral health status influence the Oral Health-Related Quality of Life (OHRQoL) of preschool children in the District of Portalegre?
NCT05756413
Early childhood caries (ECC) is a potentially painful and debilitating disease, which represents a significant public health problem among young children. There are profound disparities in ECC experiences such that children from minority and low-income families suffer a disproportionate share of the disease burden. The likelihood of parents of high-ECC risk young children seeking prevention in dental facilities is low; therefore, there is a need to increase preventive dental opportunities where these children already seek health care services. In particular, there is an urgent need to develop and evaluate ECC behavioral interventions for use in public health settings attended by high-risk children. Many authors recommend early implementation of oral health education as one means of preventing ECC. However, major issues discussed in the oral health promotion literature involve a lack of effectiveness among programs based on education alone, as well as a lack of high quality preventive interventions using evidence-based psychological and behavioral strategies. Our research team has been the first to introduce to the ECC prevention arena the self-determination theory (SDT) of motivation, internalization, and healthy functioning, proven effective in promoting positive behavioral changes in several other fields, including oral health care. The investigators have demonstrated that SDT has great promise as a motivational approach by providing evidence, based on results from our R21 (R21-DE016483) study, of the effectiveness of SDT in changing several desirable oral health behaviors for ECC prevention. Building upon the rigor of our previous experience and formative research work in the past several years, the investigators propose a Stage II NIH Model research project that will compare the efficacy of autonomy-supportive videotaped oral health messages framed by SDT to more traditional neutral videotaped messages. The investigators intend to recruit 634 pregnant mothers enrolled in Iowa Women, Infants and Children (WIC) Supplemental Nutrition Programs and follow them until their future child is 36 months old. The primary outcome of interest will be children's caries status. Secondary outcomes will be changes in children's oral health behaviors conducive to better oral hygiene and dietary habits, as well as lower levels of dental plaque and mutans streptococci.
NCT07581938
This is a prospective, cross-sectional observational study designed to evaluate the Pediatric Sleep Questionnaire (PSQ) as a screening tool for sleep-disordered breathing (SDB) risk in a pediatric dental setting. Children aged 8-13 years will be classified as low- or high-risk for SDB based on PSQ scores and compared using physiologic sleep parameters obtained from a wearable, FDA-cleared home sleep monitoring device, alongside psychosocial assessments and craniofacial measurements derived from lateral cephalometric radiographs. Findings will inform the feasibility and accuracy of incorporating validated SDB screening into routine pediatric dental care.
NCT07579403
This clinical trial had two objectives. The first was to compare the effectiveness of 950 ppm fluoride toothpaste versus probiotic toothpaste in preventing dental caries in 4- to 5-year-old children. The second was to understand how children's oral hygiene habits and dietary habits influence the development of dental caries. The main questions it aimed to answer are: * Does fluoride toothpaste reduce new caries more than control toothpaste? * Does probiotic toothpaste reduce new caries more than control toothpaste? * Which oral hygiene and dietary habits are risk factors for dental caries? Researchers compared fluoride toothpaste and probiotic toothpaste to a control toothpaste (without active ingredients). Participants were asked to complete the following tasks: * Complete a questionnaire about their oral hygiene and dietary habits at baseline * Undergo oral health examinations at baseline and after 12 months * Brush their teeth twice daily (morning and before bedtime) with their assigned toothpaste for 12 months * Use a pea-sized amount of toothpaste each time * Brush under the supervision of parents to ensure brushing quality
NCT05505084
Bone resorption after a tooth extraction is a generally accepted knowledge and has been demonstrated by many animal and human studies. Especially during the first three months followed by the tooth extraction, the volume of bone may change significantly without any interference. Thus, doing a ridge preservation procedure following the extraction is a common standard of care method to maintain the socket volume if implant placement is considered as a treatment option in the future. A variety of materials and methods have been used for ridge preservation. However, it's still inconclusive to determine the best material to maintain the ridge dimension, especially for membrane placement that allows for space maintenance to protect the grafting material. Furthermore, there is no evidence to show any treatment rationale is superior to any other ridge preservation method. In general, the membrane serves the function of the barrier and space protector. The periodontal surgeon use membranes to exclude the epithelium growth and to limit the collapse of the soft tissue into the healing alveolar socket. Regarding resorbable and non-resorbable membrane materials, both serve the function of protecting the graft material from the oral cavity. However, there are also many demonstrating that without membranes the extraction socket healed nicely without any interferences. The question to us is: Do we need the membrane to exclude the epithelium or any kind of surgical dressing material is sufficient enough to preserve the volume of the extracted ridge? The object of this study is to compare five popular membranes on the market that present different characteristics of the membranes.
NCT07551024
Some patients lose a large amount of bone in the upper jaw. When this happens, it can be difficult to place regular dental implants. In these cases, special implants called zygomatic implants can be used. These implants are longer than normal implants and are fixed in the cheekbone, which usually has enough bone to support them. They can help support fixed teeth for patients with severe bone loss in the upper jaw. Placing zygomatic implants requires careful planning and high accuracy. To help guide the surgeon during the operation, a surgical guide can be used. A surgical guide is a custom-made device that helps the surgeon place the implant in the planned position. Surgical guides can be made from different materials. The most common type is made from resin (a strong plastic material) using 3D printing. Recently, fully metallic surgical guides have been developed. These metal guides may be stronger and more stable during surgery, but it is not yet clear if they improve the accuracy of implant placement. The purpose of this study is to compare the accuracy of metal surgical guides and resin surgical guides when placing zygomatic implants in patients with severe bone loss in the upper jaw. Patients included in the study will undergo a clinical examination and a CT scan before surgery to plan the implant positions. During the surgery, each patient will receive zygomatic implants on both sides of the upper jaw. On one side, the implants will be placed using a metal surgical guide, and on the other side, they will be placed using a resin surgical guide. This allows the two types of guides to be compared in the same patient. After the surgery, another CT scan will be taken to check the final position of the implants. The planned implant position will be compared with the actual position after surgery to measure the accuracy of placement. The results of this study will help determine whether metallic surgical guides or resin surgical guides provide better accuracy when placing zygomatic implants. Participation in this study is voluntary. All patients will receive full information about the study and will sign a consent form before participating.
NCT07550179
This randomized clinical trial evaluates the risk of developing early tooth decay in patients undergoing orthodontic treatment with either traditional fixed braces or clear aligners. Because orthodontic appliances can trap plaque and make tooth cleaning difficult, patients are at a higher risk for developing early decay, such as chalky "white spot lesions" on the visible surfaces of the teeth and hidden decay between the teeth (proximal caries). In this six-month study, 24 participants are randomly assigned to receive either fixed braces or clear aligners. Researchers will monitor the participants' oral health prior to treatment, at 3 months, and at 6 months. To safely and accurately detect decay, the study uses standard visual examinations for the front of the teeth and a radiation-free optical scanner (Near-Infrared Imaging, or NIRI) to detect hidden cavities between the teeth. The primary goal of this study is to compare how many new white spot lesions and hidden cavities between teeth develop in each group over the six-month observation period. Additionally, the study tracks how these early lesions behave over time, monitors changes in the patients' daily oral hygiene, and records how often patients in each group require professional dental cleaning procedures. Ultimately, this study aims to help patients and dental professionals make better-informed decisions regarding the specific cavity risks associated with each type of orthodontic appliance.
NCT07555223
This prospective clinical study aims to evaluate the diagnostic accuracy of intraoral scans (IOS) for the detection of dental plaque and caries. The diagnostic performance of IOS will be compared with current clinical reference standards. For plaque assessment, IOS-based evaluation will be compared with plaque detection using disclosing agents. For caries detection, IOS (including white-light imaging and caries detection features) will be compared with conventional visual inspection and bitewing radiography. Adult patients aged 18 to 70 years will be included.
NCT05816525
The goal of this prospective, observational clinical cohort study is to study the effect of the preoperative condition of the tooth on the outcome of partial removal of carious tissue in mature teeth in adults. The main questions the study aims to answer are: * Do preoperative symptoms affect the outcome? * Does the depth of the carious lesion affect the outcome? One hundred participants will be recruited. Patients who meet the eligibility criteria will be asked to give their informed consent to participate in the study. Partial carious tissue removal will be performed regardless of participation in the study because selective carious tissue removal is the standard treatment of choice for a vital tooth with a deep carious lesion according to the Finnish national treatment guidelines. Participants will be asked to fill in a questionnaire regarding symptoms 7 days post-treatment. The teeth will then be followed up for 12-24 months. The null hypothesis is that there is no difference in the success between i) deep and extremely deep carious lesions and ii) initial and mild pulpitis.

NCT07509320
This systematic review aimed to synthesize current evidence regarding the prevalence, anatomical distribution, etiological determinants, and diagnostic assessment of permanent canine impaction. A comprehensive literature search was conducted in PubMed, PubMed Central, and ScienceDirect for studies published between December 2009 and December 2025. Study selection followed PRISMA 2020 guidelines. Two independent reviewers screened titles, abstracts, and full texts, and methodological quality was assessed using the Joanna Briggs Institute critical appraisal tools. Thirty-one studies met the inclusion criteria and were included in the qualitative synthesis. Reported prevalence of maxillary canine impaction ranged from approximately 0.97% to 7.10%, with mandibular impaction occurring less frequently. Palatal displacement represented the most common positional pattern. Major etiological factors included retained deciduous canines, dental arch constriction, supernumerary teeth, odontomas, and genetic anomalies. Cone-Beam Computed Tomography demonstrated superior diagnostic accuracy compared with conventional radiographic methods. The review provides a comprehensive synthesis of epidemiological patterns, etiological mechanisms, and imaging considerations associated with permanent canine impaction, highlighting the importance of early diagnosis and appropriate radiographic assessment.

Cements on the base of the calcium silicates, like Mineral trioxide aggregate (MTA), and our cement mixture ALBO MPCA, as the object of this clinical trial, have various clinical applications. In the field of dentistry, they can be used in many ways during endodontic treatment procedures of both primary and permanent teeth. The high prevalence and recurrent nature of dental caries and periodontal disease demand endodontic treatment procedures. According to the World Health Organization (WHO), the Global Burden of Disease Study 2017 reported that untreated dental caries in permanent teeth is the most common health condition among the population. It has also been reported that 2.3 billion adults suffer from dental caries of permanent teeth, and over 530 million children suffer from dental caries of primary teeth (milk teeth) across the globe. Thus, the growing prevalence of tooth decay and gum diseases is likely to favor the growth of the market during the next period. The overall prevalence of caries increases with age, and the incidence rises steeply in adults older than 30-40 years. Such a burden of caries will continue to increase with the growing ageing population. The Global Burden of Disease Study in 2016 estimated that oral diseases affected half of the world's population (3.58 billion people), with dental caries in permanent teeth being the most prevalent condition assessed, while in children aged this number accounts for about 486 million. Early identification of children who are at high risk for dental caries indicates the need for a Caries-Risk Assessment (CRA) tool. Early CRA literature confirms the value of the identification of caries as a reliable way to predict future caries. On the basis of World Health Organization (WHO) data for decayed, missing, and filled teeth (DMFT), dental decay is the most prevalent chronic disease, and it is correlated to the consumption of carbohydrates and enamel demineralization due to microorganisms. More than 90% of people suffer from this disease. WHO reported that 60% to 90% of schoolchildren all around the world suffer from dental decay, and it is more prevalent in Asian countries and Latin America. In some reports in Bosnia and Herzegovina, almost all of the examined children had caries. The DMFT index shows that the number of diseased teeth is more than 4, even in the teenage years. In Serbia, only 8.5% of the population has all healthy teeth, while 9.3% of the population is toothless. Total income related to the caries healing is about 100 Euros per inhabitant, assuming that dental health control is regular, and if only one intervention on the teeth is made during one year. This is an enormous amount of money, showing the huge economic importance of the topic. Economical estimation for Bosnia and Hercegovina show income order of several tens of millions KM, therefore, successful treatment of caries has huge importance from the financial aspect also. In Serbia is a similar situation. The application of the ALBO-MPCA in various endodontic indications is considered the essential method for significant improvement of oral health for patients with advanced periodontitis. Following the main requirements for an ideal dental cement, such as its fast setting, pretty high compressive strength, satisfactory chemistry, antimicrobial properties, and particularly high biocompatibility and non-toxicity ALBO-MPCA shows the significant advantages compared with recently used dental calcium silicate cements, particularly expressed in its extraordinary high depth of the reparative dentin bridge, approved in a wide scale of animal assays. Therefore, it will be applied in clinical trials, for the healing of the tooth canal, direct pulp capping, and other endodontic applications, typical for such kinds of medical devices. Financial support of the study is provided by the sponsor's consortium, with ALBOS as the sponsor. The recruitment site is the House Health, Foča in the Republic of Srpska, Bosnia and Herzegovina.
NCT07452614
This prospective controlled clinical trial investigates whether metabolic biomarkers measured in pulpal blood at the time of carious pulp exposure can predict the 12-month outcomes of vital pulp treatment in symptomatic permanent teeth. Eligible patients aged 16-50 years presenting with deep carious pulp exposure will undergo vital pulp therapy (partial pulpotomy or full pulpotomy). Pulpal blood samples will be collected at the time of exposure and analyzed using High-Performance Liquid Chromatography (HPLC). Treatment outcomes will be assessed clinically and radiographically at 12 months. The study aims to identify objective, measurable biomarkers that can improve pulpal diagnosis and guide clinical decision-making in vital pulp therapy.
NCT07160660
Removable partial dentures (RPD) are a well-established treatment option for the prosthetic rehabilitation of partially edentulous patients. They are retained at the remaining natural teeth by clasps to provide functional stability. As an alternative to clasps extacoronal adhesive attachments are fixed to the abutment teeth using adhesive cementation techniques. These adhesive attachments improve retention and stability of the prostheses and are indicated when the patient requires a non-visible retention element and healthy coronal tooth structure is available as a prerequisite. In clinical practice, extracoronal adhesive attachments offer a minimally invasive and aesthetic anchoring alternative of removable dental prostheses associated with higher costs compared to a common clasp retention. As a result, adhesive attachments are relatively rarely used and are technically sensitive both in the clinical realisation and in terms of the dental technology. Hence, limited scientific data are available regarding their long-term clinical behaviour, but no data is available about patients' satisfaction with such extracoronal adhesive attachments. This research project aims to investigate patients' satisfaction with extracoronal adhesive attachments (group A) of removable dental prostheses in comparison to clasps (group B), and to investigate the short- and long-term clinical performance of both treatment options. This is a non-interventional observational study. Only routine clinical examinations are performed. No additional risks or burdens arise for participants. All measures fall under minimal risk A according to ClinO, Art. 61. Overall risk: Minimal. No invasive procedures or biological sampling. Ethical and legal standards are fully met. Sex and gender dimensions are not relevant to the topic of the study as the population is determined by patients treated since 2001 and cannot be influenced by the study design.
NCT07209696
This study is designed to evaluate strategies for reducing dental anxiety in pediatric patients. The commonly applied "Tell-Show-Do" method involves explaining and demonstrating dental procedures before they are performed. In this randomized controlled trial, three groups of children will be compared: Children who receive only the Tell-Show-Do method, Children who are prepared at home with a storybook prior to receiving the Tell-Show-Do method, Children who are prepared at home with an animation video prior to receiving the Tell-Show-Do method. Children's dental anxiety will be assessed using validated behavioral observation scales, including baseline measurement at the first examination, after preparation, and following completion of dental treatment. The study will determine whether the addition of a storybook or an animation video provides greater effectiveness in reducing dental anxiety compared with the Tell-Show-Do method alone.
NCT07212660
The overall aim of this clinical investigation is to assess the clinical performance and safety of composite restorations cured with fast curing mode (5 seconds with 2000 mW/cm²) in primary molars.
NCT07476417
Mowat-Wilson Syndrome (MWS) is a rare syndrome characterized by the presence of facial gestalt and delayed psychomotor development, variably associated with intellectual disability, epilepsy, Hirschsprung's disease (HSCR) and multiple congenital malformations. Although there is evidence of the presence of dental and craniofacial anomalies in MWS, little epidemiological data is available to date. The goal of this observational study is to assess oral health and dento-facial phenotype of people affected by Mowat-Wilson Syndrome (MWS). In addition, the Oral Health Related Quality of Life (OHRQoL) will be investigated.
NCT06709352
The aim of this analytical cross-sectional study study is to evaluate the prevalence of root caries in senior patients of both genders age of 50 to 70 years old, taking antihypertensive drugs attending the Cairo University Dental Educational Hospital and to consider the association of root caries with antihypertensive drugs. Furthermore, to understand the relationship between risk indicators of root caries and saliva pH that can be a potential etiological factor. \- The main question it aims to answer is: In senior patients attending Cairo University Dental Educational Hospital, what is the prevalence of root caries among patients taking antihypertensive drugs, what are the related risk indicators and how do they correlate with salivary pH?
NCT07191262
This study will compare commercially available, commonly used mouth rinses (0.12% chlorhexidine (CHX) vs. Ethylenediaminetetraacetic acid (EDTA)) for immediate post-operative and daily antiseptic use after tooth extraction and ridge preservation grafting followed by daily use of commercially available an essential oil (EO) mouthrinse and EDTA mouthrinse.
NCT06430957
Obstructive sleep apnea (OSA) is a sleep-related respiratory dysfunction. The prevalence of OSA is increasing with the increasing rates of obesity and elderly population worldwide. Perioperative anesthesia management should be adjusted to improve patient safety in patients with OSA. In OSA patients, positive pressure ventilation support may be required in the preoperative period, various ventilation strategies may be required in the intraoperative period, different pharmacologic agents may need to be avoided, and intensive care unit follow-up or noninvasive ventilation support may be required in the postoperative period. However, it is reported that a significant percentage of OSA patients remain undiagnosed. ASA (American Society of Anesthesiologists) has reported the criteria that should be questioned in order to determine the risk of patients in terms of OSA and to initiate the diagnostic process in risky patients and to make appropriate anesthesiologic arrangements in the perioperative period. In addition, the STOP-BANG assessment scale, which is widely used all over the world in OSA risk assessment, is also used in OSA risk assessment. It is thought that dental caries and extraction needs may be higher in OSA patients, especially since open-mouth sleeping accompanies the situation. In this respect, it is also important for patients to be diagnosed with OSA as it may prevent dental damage due to open-mouth sleeping in the future. Identifying patients at risk for OSA and directing them to the diagnostic process is very important for patient safety. Within the scope of the study, the criteria recommended by ASA and STOP-BANG score will be evaluated and recorded. Risk stratification in terms of STOP-BANG questionnaire and ASA criteria will be done separately for each patient and for each classification method. Patients at high risk will be consulted to the relevant medical department in the preoperative period for further investigation and treatment. In addition, it is aimed to correlate the risk levels determined in the study with postoperative respiratory complications and recovery time.
